As some people said down in the Wolverine forum, if TW can make $400m+ WW, then DOFP should be able to hit $600m at least. I'd be willing to say $700m for now.

I think TW did that mostly from OS expansion. It didn't really light the world on fire domestically. And there's probably a high degree of overlap between the 2 sub-franchises so I don't think you'll see such a huge jump there. Maybe DOFP makes 110-115%of the OS number that TW did. So what's going to really make the difference is domestic. Let's say it does another $100M DOM over what TW did, which is believable, then you're still looking at mid $500M WW range or so with $600M as a good number for a ceiling.

Somewhere in the $700-800 million neighborhood is where I'm placing my bet. I think there's also a chance the stars could align with a great promotion campaign from Fox (awesome trailers, commercials, posters, etc.), great reviews, hype, word of mouth, and so on... could lead to a $900 million gross. Difficult thing to predict a year ahead or even one week ahead of the premiere, but it's always fun to see the predictions of others.

I'm going to go with 700-800 million worldwide. If Wolverine made more than 400 I'm pretty sure Days of Future Past can almost double it being such a big production with a humongous list of cast members and characters -some of them being way more famous than when they started- plus the whole concept of merging the two timelines/franchises plus the return of Singer or even the 3D factor.

I would go for more but since the X-men movies don't have the best box office track record I'm sticking to something more grounded for now. Wouldn't be surprised if it did more though. I guess it all comes down to promotion which so far it's going really well and word to mouth which depends of course on how good the film will end up being.

I'm really curious to see how promotion of the sentinels plays with the general audience. I think a lot of people have no idea what's coming.

Yeah, I've been saying that we have seen nothing yet. By the time the effects are done, we can expect the action, the power displays and the wow factor. The first trailer is mysterious in a way, because there is an implied danger but we can't see it yet.

At the moment, I would only assume that Hugh, Halle, and Jennifer are box office draws. Ian and Patrick and maybe even Dinklage have a cult following. James and Fassy are doing great work (with Fassy in particular having lots of buzz), but they haven't had box office hits outside of genre movies.

All combined, they do bolster each others' star power, but the main draw is still the X-Men brand name, the familiar characters, the action/ effects, and finally... a few big name stars.

In China Ellen Page ,James and Fassy are more popular than Halle and Patrick ..Things may be different in Asia.
